In the final draft script of "Similitude", Tucker was established as having fixed his father's ocean skimmer, pointing out to his father that an out-of-phase suspensor coil had been the reason why the craft hadn't been working properly.

Tucker used to take his younger sister, Elizabeth, to a movie theater near their house. He later remembered that she would "scream like a banshee" if he didn't take her. (ENT: "The Expanse") Tucker once put a garden snake in his sister's doll house, and his family once had a large dog named Bedford. (ENT: "Similitude")

On several occasions, Tucker went on camping trips with his friends. They would spend half the night looking up at the stars and wondering what Earth's sun would look like from a distant planet. (ENT: "Strange New World")

During his early childhood, Tucker attended Bayshore Elementary, where he attended his first dance. He knew before the event that Melissa Lyles, a girl who he had a crush on, would be there, and spent weeks practicing dance steps with his brother in preparation for the event. On the night of the dance, Melissa wore a red dress, and Tucker believed she was the prettiest girl there. He desperately wanted to ask her to dance with him, but he was not courageous enough to approach her. Tucker caught the girl looking at him a few times, but he eventually ended up standing in a corner with his friends. Twenty years later, he still regretted not asking the girl to dance. (ENT: "Fusion")

Tucker as he appeared at age seventeen

In Tucker's tenth grade biology class, a Vulcanscientist who the children referred to as "Mr. Velik" came to teach the class about life on other worlds. Tucker, who had never seen a Vulcan up close before, was terrified of the teacher. Velik often reminded his students, "Challenge your preconceptions or they'll challenge you." Tucker went on to associate this advice with his memory of Velik. (ENT: "Strange New World")

Tucker did his survival training during two weeks in the Australian Outback in a group that included Archer. (ENT: "Desert Crossing") Additional Starfleet training simulations familiarized Tucker with mind-altering agents. (ENT: "Strange New World")

Tucker was part of the away team that became infected by the pollen of the plant life on a deserted planetEnterprise was exploring. The pollen caused paranoid and delusional behavior in the away team; Tucker thought that each member was trying to kill him. (ENT: "Strange New World")

Tucker's pregnancy

In the course of first contact with the Xyrillians, Tucker boarded their ship to fix their engines. The physical environment was considerably different to his usual and Tucker found acclimatisation difficult. During his stay on their ship he developed a relationship with Ah'len, an engineer. After the ship left, Tucker discovered he was pregnant. Although he had not knowingly had a sexual encounter, a game he and Ah'len played that enabled them to read each other's minds may have served as a medium to transfer genetic material. While Tucker was the first Human male to become pregnant, as well as the first known Human participant in interspecies reproduction, DoctorPhlox said the embryo was not techinically Tucker's child, but that he was simply serving as a host. When the ship was tracked down, the embryo was successfully transferred to another host. (ENT: "Unexpected")

Brannon Braga believed Tucker's difficulty with adapting to conditions aboard the Xyrillian ship helped show him as different to characters from later in Star Trek chronology, Braga commenting, "That's the kind of stuff you would never see a Riker do, because they're just too seasoned." (Star Trek: Communicator issue 139, p. 23)

On a mission to Coridan, Tucker and Reed attempted to rescue Archer and T'Pol from rebel forces, but were captured themselves. They were freed by the Andorian Shran and his men, who helped Tucker and Reed rescue T'Pol and Archer. (ENT: "Shadows of P'Jem")

Tucker and Reed became stranded in a shuttlepod after they mistakenly believed Enterprise was destroyed when they found debris at the coordinates where they were supposed to meet the ship. In reality, the debris was from another ship, the crew of which Enterprise had rescued and was transporting back to their planet. With their air running out, Tucker jettisoned the impulse engines as a flare, which Enterprise saw and thus was able to come to their rescue. (ENT: "Shuttlepod One")

The Ferengi hijacked Enterprise after rendering the crew unconscious. Tucker, who was in a sealed compartment, was not affected. He woke T'Pol, and both worked to play the Ferengi against each other, trapping them and regaining control of the ship. (ENT: "Acquisition")

Tucker was captured by a symbiotic creature which had stowed away on Enterprise. The creature integrated Tucker's nervous system along with other crewmembers it captured to its own system, but after the crew learned that the creature wished to return home to reunite with its main host, it released Tucker and the others. (ENT: "Vox Sola")

Tucker, as part of an away team to salvage an abandoned ship on a planet, found that there was a settlement there. They were called the Kantare; after their ship crashed, they were stranded on the planet. Tucker became romantically involved with Liana, but it was discovered that the settlement was a hologram created by Liana's father, Ezral, to keep his daughter company. (ENT: "Oasis")

Tucker and Archer, after helping to repair Zobral's ship, were invited to visit his village. Zobral was really a rebel fighting against an oppressive government, and when the village was attacked, Tucker and Archer became stranded in a vast desert until they were rescued with help from Zobral. (ENT: "Desert Crossing")

While attempting to discover the powers of an automated repair station Enterprise had entered, Tucker was transported off the station back to Enterprise in an effort to stop the investigation. He later discovered that the station was using humanoid lifeforms to power its computer. (ENT: "Dead Stop")

Tucker saved an alien princess, Kaitaama, from kidnappers, and had a brief romantic relationship with her during the rescue. (ENT: "Precious Cargo")

Tucker and Zho'Kaan on the moon's surface

Tucker became stranded on a barren moon with an Arkonian who had tried to shoot his shuttle down. At first, they tried to kill each other, but realized that the only way they could survive was to cooperate with each other. Zho'Kaan's dehydration was causing cellular breakdown, which made using the transporter not an option. Tucker refused to leave him, and cared for him until a modified Arkonian shuttle rescued them. (ENT: "Dawn")

When three aliens who boarded Enterprise warned that a deadly neutronic wavefront was quickly approaching and the crew needed to take shelter to be protected from the storm's deadly radiation, Tucker suggested that the one heavily-shielded place on board that might suffice for the eight-day ordeal was the cramped quarters of the catwalk, the maintenance shaft that ran the length of each nacelle. While they were in the catwalk, alien intruders attempted to steal Enterprise, and Tucker helped drive them off. (ENT: "The Catwalk")

During a stop at a medical conference, Tucker met Feezal, Phlox's wife. Feezal became attracted to him and tried to seduce him, and when Tucker told Phlox about this, he was told by Phlox that he should have taken advantage of Feezal's offer. While assembling a neutron microscope Feezal delivered, Tucker bragged he could put back together just about any equipment he had ever met. (ENT: "Stigma") Later, Tucker and Reed discovered that a derelict ship Enterprise salvaged was from the future. Even the few papers he read on spatial geometry could not explain the ship's dimensions. (ENT: "Future Tense")

In ultimately unused dialogue from the final draft script of "Stigma", Tucker commented about his difficulty in trying to operate the neutron microscope, "I'm a pretty quick study when it comes to these kinds of instruments... but this one's a doozy." [1]

While investigating an alien ship, Tucker's body was invaded by an alien wisp that began to control his actions. Their plan was to take over the bodies of the crew and steal Enterprise. (ENT: "The Crossing")

The Vulcans and Andorians were again involved in a dispute over a planet, Weytahn. While Archer tried to mediate the dispute, Tucker, commanding Enterprise, stopped the ships of both sides from engaging in battle when he steered Enterprise between the two fleets, giving Archer time to settle the dispute. (ENT: "Cease Fire")

Tucker and Archer were unjustly sentenced to the penal colony of Canamar. A prisoner, Kuroda, took over the ship and enlisted Tucker and Archer's help in escaping. His plan was to transport off the ship to another he was meeting, and crash the ship along with the other prisoners and guards. Tucker and Archer foiled his plan, and were rescued by Enterprise. (ENT: "Canamar")

Tucker led an away team to rescue three Denobulangeologists from the planet Xantoras. The government had ordered all aliens to leave their world immediately, and Tucker had to persuade the geologists to leave. (ENT: "The Breach")

Reed and Tucker look for any sign that his sister might be alive in Xindi-devastated Florida

Tucker's encounter with the Vissians proved costly. The Vissians used a cogenitor, a third gender, to reproduce; these cogenitors were treated as an inferior class with no rights. After meeting with a cogenitor, Tucker found that it had the same mental capabilities as the other Vissians, and took it upon himself to convince the cogenitor he met to fight for her rights. He also secretly taught the cogenitor how to read, play go, and educated it about its rights as an individual. The cogenitor chose the name "Charles" for itself, in honor of Tucker. Later, it asked for asylum on Enterprise, which, after several meetings, was denied. Archer finally decided that to grant asylum would ruin any chance of Starfleet making successful trade with the Vissians. Several days later, Tucker was informed that the cogenitor had killed itself, and blamed himself for the suicide. (ENT: "Cogenitor")

Tucker became bitter after his sister's death, and was full of hatred and revenge. His mental state led to many sleepless nights. Phlox tricked Tucker into taking Vulcan neuro-pressure from T'Pol; this helped him sleep properly, and moved his relationship with T'Pol to another level. Tucker's first contact with the Xindi occurred at a mining camp where a Xindi, Kessick, was rescued. Kessick was killed in the escape, but gave the coordinates of the Xindi homeworld before he died. (ENT: "The Xindi")

Commander Tucker in 2153

An away team consisting of Captain Archer, T'Pol, Lieutenant Reed, and EnsignHoshi Sato was endangered on the homeworld of the extinct Loque'eque race when a virus left on the planet mutated Archer, Reed and Sato into the lost species. When another alien race landed on the planet, determined to exterminate any of these species, Tucker led a MACO team to stop the alien exterminators and rescue the away team. (ENT: "Extinction")

Tucker and T'Pol tried to replicate trellium-D, a substance that would protect Enterprise from the Delphic Expanse's deadly anomalies. The attempt ended in an explosion. (ENT: "Rajiin")

In a scene which was included in the final draft script of "Rajiin" but is not in the final edit of the episode, it would have been implied that, as of the timing of the installment, Tucker had been sleeping not badly but not particularly well either.

Tucker attempted to "rewrite the book on warp theory" once he realized the Cochrane equation wasn't constant in the Expanse, with spatial gradients destabilizing the warp field. Eventually, he succeeded, as he rerouted the system taps, compressing the antimatter stream before it entered the injectors, thus stabilizing the warp field. (ENT: "Anomaly", "Similitude")

In unused dialogue from the final draft script of "Similitude", Tucker admitted to T'Pol that he "[could] hardly wait" to test the modifications in "the first big test" of them, which was scheduled for 0800 the next day.

Tucker was badly injured, ending up in a coma, due to a primary injector flare during an encounter with a polaric field. He was cloned using a mimetic simbiot in an attempt to harvest brain tissue from the clone in order to save his life. The clone, Sim, attempted to escape Enterprise to save his own life, but decided against it at the last minute and allowed Phlox to transplant the tissue even though it meant his death. (ENT: "Similitude")

In ultimately unused dialogue from the final draft script of "Similitude", a comatose Tucker was referred to, by Doctor Phlox, as being "on full autonomic life support".

After recovering a small craft in the Expanse with an unknown alien in it, Tucker determined that the alien was a test subject to see what effects the atmosphere would have on it. This was the first indication that an alien force was behind the Xindi and their attack on Earth. (ENT: "Harbinger")

After coming in contact with a Xindi-Insectoid ship, Tucker questioned Archer's ability to captain Enterprise after Archer had been infected with a toxin that made him believe he was the caretaker to the eggs of the Xindi-Insectoids, and was endangering the mission. Tucker led the crew in a mutiny to retake the ship from Archer before he could be cured. (ENT: "Hatchery")

In the final draft script of "Hatchery", Tucker's dilemma of whether to mutiny against Archer was described as "the most difficult decision of his [i.e., Tucker's] career."

Tucker piloted a captured Xindi-Insectoid shuttle and discovered the location of the Xindi weapon. In the battle of Azati Prime, Enterprise took heavy damage and lost eighteen crewmen. Tucker was terribly affected, and it did not help when he had to compose letters to the families of the slain crewmembers, a task that reminded him of his sister's death. To make matters even worse for Tucker, he found it extremely difficult to forgive Degra, one of the Council members of the Xindi who had designed the Xindi weapon, and had a couple of tension-filled encounters with him, as Archer was trying to gain Degra's trust. Eventually, however, the experience of consoling others helped Tucker finally deal with Elizabeth's death. (ENT: "Azati Prime", "The Forgotten")

After an accident using Xindi subspace corridors, Enterprise met its future counterpart. Enterprise's counterpart was captained by Lorian, the son of Tucker and T'Pol. The crew of the future Enterprise helped Enterprise keep an appointment with Degra, so peace could be discussed. (ENT: "E²")

Tucker destroys one of the Delphic Expanse Spheres

Tucker played a large role in the final battle with the Xindi. He destroyed one of the spheres that disrupted the energy field that the Sphere-Builders, who were behind the Xindi attack, were using to help the Xindi; this gave time for Archer and the MACOs to board the weapon, destroy it and save Earth. (ENT: "Countdown", "Zero Hour")

On returning home to a hero's welcome, Tucker faced heartbreak when he traveled to Vulcan and witnessed T'Pol's marriage to Koss. (ENT: "Home")

In 2154, the Augment crisis began. Dr. Arik Soong had genetically engineeredHuman embryos; reaching adulthood, these Augments attacked a Klingon ship and killed the crew. When the Klingons demanded justice, Enterprise was dispatched to capture the Augments, with Soong on board to help them. After T'Pol was captured by the Orions and sent to a slave market, Tucker was able to decode a neural restraint and free her. He discovered that the Augments had captured Cold Station 12, where other Augment embryos were stored, and took part in the operation to retake the Augments' ship and stop the threat. (ENT: "Borderland", "Cold Station 12", "The Augments")

Following the destruction of Earth's embassy on Vulcan, Archer and T'Pol searched for the Syrrannites, who were believed to be the perpetrators, on Vulcan's surface, leaving Tucker temporarily in command of Enterprise. With help from AmbassadorSoval, Tucker uncovered a conspiracy in which the Vulcan High Command attempted to cover-up the bombing as well as launching a preemptive strike against the Andorians, who they believed had constructed a devastating weapon based on Xindi technology. Tucker warned Shran, and participated in the engagement between the Vulcan and Andorian fleets. (ENT: "The Forge", "Awakening", "Kir'Shara")

Tucker was infected with a silicon-based virus while part of a landing party on a planet's surface, looking for salvage amongst Klingon waste. Although Tucker initially died due to the virus, he was resurrected by two Organian observers, who were watching the crew's reaction to the virus. (ENT: "Observer Effect")

On November 12, 2154, Enterprise was escorting a group of Tellarites to a conference with the Andorians to settle long-standing disputes. However, the Andorian ship was destroyed by what appeared to be a Tellarite ship. Among the survivors was Shran. The Tellarites denied any involvement, and then Enterprise was attacked by an Andorian ship. In reality, the ship was a Romulan drone ship piloted by a neural interface. This was an attempt by the Romulans to start war among potential allies. Tucker and Reed transported over to the ship and discovered that it was unmanned. They attempted to sabotage the ship and after doing so, ejected out into space where they could be transported back aboard Enterprise. Tucker built a telepresence unit for Enterprise in order to prepare it for battle against the Romulan drone ships. The Romulans' plot was foiled with the cooperation of Humans, Tellarites and Andorians; this would be the foundation for a federation of planets. (ENT: "Babel One", "United", "The Aenar")

Tucker transferred off Enterprise to Columbia NX-02 due to his feelings for T'Pol. He later returned to Enterprise to help them deal with the Klingons, who faced extinction due to a genetic virus caused by their experiments with Augment DNA. (ENT: "Affliction") Tucker transferred back to Enterprise permanently shortly after an encounter with Orion females who attempted to take over the ship by influencing the minds of the male crew; he proved to be immune due to his new-found psychic bond with T'Pol. (ENT: "Bound")

Terra Prime, a xenophobic terrorist faction led by John Frederick Paxton, threatened to disrupt a conference to form a coalition of planets, and had created a clone using the DNA of Tucker and T'Pol, with the plan of using the child to stir anti-alien feelings. When Tucker and T'Pol tried to infiltrate Terra Prime, they were captured and taken to a secret base on Mars. From there, Paxton threatened to attack Starfleet Headquarters with a laser cannon unless all aliens left the Sol system. Tucker tried to sabotage the weapons system, but was discovered and thrown into a cell. He escaped and was able to meet with a team from Enterprise who had come to rescue him and T'Pol. Tucker led them to Paxton's complex where they were able to deactivate his weapon and end his threat. Sadly, the child, whom T'Pol named "Elizabeth" after Tucker's deceased sister, died due to a flaw in the procedure used in her creation. It was initially believed that the causa mortis was an incompatibility between the Vulcan and Human DNA, a hypothesis Doctor Phlox shortly afterward determined to be wrong. (ENT: "Demons", "Terra Prime")

Tucker continued serving as chief engineer aboard Enterprise until 2161, when the ship was scheduled to be decommissioned prior to the signing of the Federation Charter. En route to Earth to attend the founding ceremony of the alliance that would give birth to the United Federation of Planets, Enterprise made a detour to Rigel X to rescue Shran's daughter, Talla. Tucker participated in the rescue operation. Knowing Archer's importance to the upcoming ceremony, he attempted to persuade Archer to remain aboard Enterprise, as it was safer, but Archer insisted on joining the mission. Ironically, it was Tucker himself who was nearly killed on the mission when the catwalk he was on was shot out from under him. Fortunately, Archer was there to save him, and the mission was successful.

Tucker's final moments

Unfortunately, the victory ultimately came at the cost of Tucker's life. Shortly after Enterprise left Rigel X, Talla's abductors somehow managed to board the ship. When the alien trespassers threatened Archer, Tucker quickly thought up a plan to lure the aliens away from Archer. Despite orders from Archer to remain quiet, he insisted and persuaded one of the aliens to render Archer unconscious. With his captain safe and no longer in the way, Tucker lured the aliens away to a nearby plasma junction, which he claimed was a communications system which he would use to contact Shran in order to bring him to the aliens. With the intruders fooled, Tucker rigged the junction to explode, killing the alien trespassers. However, Tucker was also critically injured in the explosion and he ultimately died, having sacrificed himself for his captain. (ENT: "These Are the Voyages...")

Following Tucker's sacrifice, Archer ultimately went on to be an instrumental figure in the formation of the United Federation of Planets.

In 2370, CommanderWilliam T. Riker of the USS Enterprise-D used historical records of the events surrounding Tucker's death in a holodeck simulation to help sort through a personal moral crisis related to the USS Pegasus, a ship he once served on. The historical events used in the program included the mission to Rigel X to save Shran's daughter and Talla's former captors storming Enterprise. After seeing Tucker give his life to save Captain Archer, disobeying Archer's orders in the process, Riker decided he, too, would do the right thing regardless of the cost. (ENT: "These Are the Voyages...")

Tucker had many likes and interests, ranging from personal to professional, especially in the engineering field. He often enjoyed studying alien engines, or even certain Human ones. In 2151, Tucker was in awe of the Vulcan ship Ti'Mur and its ringed-engine drive. Unfortunately, Vulcan engine schematics were classified. Later that year, Tucker was interested in visiting the legendary Coridan Fleet Yards, rumored to build starships capable of warp 7. Other alien species with engines he was particularly amazed by were those of Zobral's species and the Vissians. (ENT: "Breaking the Ice", "Shadows of P'Jem", "Desert Crossing", "Cogenitor")

Tucker's favorite dessert was pecan pie. After a long day of work, Tucker said it was all worthwhile to come to the mess hall for a slice of it. He even suggested that T'Pol might like it. (ENT: "Breaking the Ice") On a separate occasion, he noted that his favorite dessert was key lime pie. (ENT: "Similitude")

Tucker's favorite food was pan-fried catfish. His mother made it perfectly and if anyone asked his favorite food, Tucker would say that she would "give you the recipe for pan-fried catfish and not let you leave until you promised to cook it right." (ENT: "Silent Enemy", "Dead Stop", "These Are the Voyages...")

Another of Tucker's interests was ancient cinema. Upon signing on to Enterprise, he suggested they have a "movie night," which often served to help crew morale. Although, since he chose the movies, some of the crew often complained about his selecting what seemed like the same movie plots over and over, often from the middle of the 20th century. (ENT: "The Catwalk", "Cogenitor")

Hailing from Florida, Tucker went diving in the ocean before he joined Starfleet. He kept a picture of himself scuba diving in his quarters, as well an old-style skin-diving suit helmet. (ENT: "These Are the Voyages...")

Tucker's initial job as first officer was to be the liaison between the captain and the crew. Even though the position was later given to Sub-CommanderT'Pol, Tucker was still well-liked by most of his shipmates.

On the first day of Enterprise's voyage, some friends in the mess hall invited him to sit with them for dinner, but he reminded them that he had plans: dinner with Captain Archer in the captain's mess. (ENT: "Broken Bow")

The two officers met when Jonathan Archer was a commander in the NX Program and Tucker was a lieutenant on Captain Jefferies' engineering team. After the first NX prototype, the NX-Alpha, was destroyed and the project was going to be canceled, Tucker and Archer teamed up with Commander A.G. Robinson to save the program. They launched the NX-Beta, the second NX prototype, without permission, and were ultimately successful. (ENT: "First Flight")

Tucker and Archer began to develop a strong bond of friendship, enduring harsh survival training in the Australian Outback together and saving each other's lives many times. During an Omega training mission on Titan, Tucker's EV pack froze up and he got nitrogen narcosis. He tried to remove his helmet, but Archer ordered him to keep it on. Later, in 2152, Archer saved a delirious Tucker from heatstroke when they were stranded in the Torothan desert. Likewise, Tucker rescued and saved Archer's life quite a few times. He saved him from execution on a pre-warp alien planet, after Archer and Lieutenant Malcolm Reed tried to find a communicator left behind. Tucker also rescued Archer from bounty hunters who wished to turn Archer over to the Klingons. (ENT: "Desert Crossing", "The Communicator", "Bounty")

Tucker was always there when the captain needed cheering up. When Archer was depressed about Enterprise's botched first contact with the Kreetassans, his chief engineer lightened the mood with a data module of the Stanford versus Texas water polo match. They ate their meals together, and shared many interests. (ENT: "Vox Sola")

A note in the final draft script of "Vox Sola" remarked, "Trip always has a way of cheering his friend up, despite the circumstances."

This did not mean that their relationship was always stress-free. Tucker once interfered with the Vissians' customs; the Vissians used a third gender, called a cogenitor, for reproduction, and Tucker persuaded one such being that it was being treated unfairly. Archer was furious, and told Tucker that he was in no position to judge the fairness of the Vissians' culture. When the cogenitor was later denied asylum on Enterprise and committed suicide, Archer told Tucker that he hoped he had learned his lesson about interfering. (ENT: "Cogenitor")

Tucker and LieutenantMalcolm Reed formed an unlikely friendship. They were polar opposites: Reed was stuffy and all work as opposed to Tucker's zest for life. When the duo was stranded in a damaged shuttlepod for several days, they initially clashed, but discovered that they had more in common than they thought. At one point, Tucker even tried to sacrifice himself so that Reed would have a better chance of survival. Luckily, they were both rescued by Enterprise. (ENT: "Shuttlepod One")

Tucker and Reed shared a unique shore leave together on the pleasure planet Risa when the two went in search of fun at a Risian nightclub and picked up two beautiful aliens. The women turned out to be morphs who robbed them, not only taking their money, but also their clothes. Tucker and Reed managed to escape, but promised not to tell their fellow crewmembers about the incident. (ENT: "Two Days and Two Nights")

It is loosely implied, though not specifically stated, that this was the same class as Miss Malvin's fourth grade class in Kenmare, County Kerry, Ireland that sent drawings and letters and that a transmission answering questions was sent back later, though it could have simply been two different classes. It's not unreasonable to assume that schools across the planet were also doing this.

Tucker was very close to his younger sister, Elizabeth ("Lizzie"), and was traumatically affected by her death in the Xindi attack in 2153. (ENT: "The Expanse", "The Xindi") He later recalled he had been so profoundly affected by her death there were times when he just wanted to close up and retreat inside himself. (ENT: "Daedalus")

In the final draft script of "Daedalus", Tucker admitted that actually retreating into himself "just made it worse", though he doesn't state this in the final version of the episode.

When CrewmanJane Taylor was killed in the Battle of Azati Prime, Tucker found it was his responsibility to write a letter to her family. While writing it, he kept transferring his feelings of loss from Lizzie to Jane, and mentioned how she "died too young." Eventually, Tucker was able to overcome this and finish the letter. (ENT: "The Forgotten")

In an ultimately discarded line of dialogue from the writers' second draft script of "Breaking the Ice", Tucker admitted to having had "a couple" of long distance relationships which had "ended badly."

When he noticed a story note on a board in the writing staff's offices which stated, "Phlox/Trip/Trisexual", Tucker actor Connor Trinneer was extremely worried that Tucker would be depicted as having an affair with Phlox. Trinneer was meanwhile unaware Tucker was instead intended to have a relationship with a cogenitor in the episode "Cogenitor", which was what the note actually referred to. (Beyond the Final Frontier, p. 380)

Before Enterprise was launched, Tucker was dating a woman named Natalie, from Florida. He was unable to say goodbye to her before the ship launched, but wished he would have gotten the chance to, face to face, after receiving a "Dear John" letter. He said maybe he would get a chance to, when Enterprise headed home after being rendered defenseless by a mysterious alien vessel. (ENT: "Silent Enemy")

In mid-2151, Tucker had a brief, unintentional sexual encounter with a Xyrillian female named Ah'len, which resulted in Tucker's inadvertent impregnation. Ah'len assumed that Tucker would be physically incompatible with her people. Tucker became the first Human male to become pregnant, as well as the first known Human participant in interspecies reproduction. (ENT: "Unexpected")

When his sister died in the Xindi attack on Earth in 2153, Tucker experienced difficulty sleeping due to nightmares about the event. He was assisted in recovering from these difficulties by Sub-Commander T'Pol's application of Vulcan neuro-pressure. Over the course of their neuro-pressure sessions, Tucker began to develop feelings for T'Pol. They finally admitted it to one another in January of 2154, though T'Pol later denied her emotions. (ENT: "The Xindi", "Harbinger", "E²")

After Enterprise was heavily damaged at Azati Prime in February 2154, Tucker threw himself into repairing the ship, going two straight days with no sleep until DoctorPhlox forced him to take a few hours' rest. He was haunted by visions of Crewman Jane Taylor, a member of his engineering team who had died in the battle with the Xindi. Tucker was supposed to be writing a letter of consolation to her parents, but was unable to do so, as Jane reminded him so much of his sister. Finally, with T'Pol's help, Tucker was able to work his way through the grief he felt concerning both his sister and Crewman Taylor. (ENT: "The Forgotten")

When Enterprise returned to Earth, Tucker accompanied T'Pol on a visit to Vulcan and her mother, T'Les. While on Vulcan, he was forced to put his emotions aside and watch T'Pol marry Koss for political reasons. Even when Koss later divorced T'Pol, Tucker was torn as she showed no interest in rekindling their relationship. (ENT: "Home", "Kir'Shara")

In November 2154, Tucker decided that his unrequited feelings for T'Pol were interfering in the performance of his duties. He left Enterprise, accepting a request from CaptainErika Hernandez to join the crew of Columbia NX-02, which was launching behind schedule due to engine trouble. With his help, the ship was ready to go in a few days. (ENT: "The Aenar", "Affliction") Shortly after, Tucker transferred back to Enterprise, at the same time as discovering that he and T'Pol shared a psychic bond as a result of their previous mating - which he stated wasn't that big of a deal, although he did insist until she admitted that she wanted him back. (ENT: "Bound")

In January 2155, Tucker and T'Pol discovered that they had a daughter that was created with their stolen DNA by Terra Prime. (ENT: "Demons") After rescuing her from Terra Prime, they decided to call her "Elizabeth", after Tucker's late sister, but they were heartbroken when it was discovered that there was a flaw in the procedure used in creating Elizabeth, and she died. (ENT: "Terra Prime")

In ultimately excised dialogue from the final draft script of "Dawn", Tucker mentioned that he regretted not having learned T'Pol's age, during Enterprise's voyage (up to that point).

Brannon Braga was pleased with how Tucker's relationship with T'Pol develops in the episode "Harbinger", believing "the Trip-T'Pol arc" in that episode "is super-sexy and surprising." The dynamic between Tucker and T'Pol in "E²" was also a highlight in Braga's opinion. (Star Trek: Communicator issue 151, pp. 32 & 34)

In the final draft script of "Twilight", the 2165 version of Tucker was described thus; "He's not the same easy-going officer we remember. He's been in command of Enterprise for almost a decade, and has the air of a seasoned and experienced Starfleet Captain."

In a different alternate timeline where Enterprise was stranded in the year 2037, Tucker married T'Pol in a traditional Vulcan ceremony; it took Tucker weeks to learn how to pronounce the vows. Afterward, they honeymooned in Cargo Bay 3, which had been filled with sand gathered from an asteroid and a palm tree manufactured by Tucker. They had a son named Lorian, but unfortunately, Tucker died when his son was only fourteen years old. (ENT: "E²")

"I assume you were watching the attack – calculating the blast yields. Boy, you must have been pretty damned excited. I mean, that beam cut one hell of a swath through Florida. That's the name of one of the places you destroyed, Florida. Did you actually see the cities burning, the houses, the people being vaporized? You know, I had a sister there..."

- Tucker, to Degra, before he is cut off by Captain Archer entering the room (ENT: "The Forgotten")

"Every time I start, I hear myself saying what a fine young woman she was – how smart and full of potential. And I realize, I'm not thinking about Taylor at all, I'm thinking about Elizabeth."

- Tucker, to T'Pol, finally realizing why he is having so much trouble writing a letter to Crewman Taylor's parents (ENT: "The Forgotten")

Tucker's nickname was initially planned to be "Spike". ("Broken Bow" audio commentary, ENT Season 1 DVD) At one early stage, he was also intended to hold the rank of lieutenant. A character description of Tucker was meanwhile written into the series bible for Star Trek: Enterprise, referring to him as having the nickname "Spike" and the rank of lieutenant. The document elaborated by describing him thus; "Chief Engineer. Early 30's. A Southerner who enjoys using his 'country' persona to disarm people. He has an offbeat, often sarcastic sense of humor. Although Spike is a brilliant engineer and an outstanding officer, he has very little first-hand experience with alien cultures, and he's often a 'fish out of water' when dealing with new civilizations." While Tucker's nickname was still to have been "Spike" though his rank had changed to commander, a character breakdown sheet that Paramount sent to talent agents, upon seeking an actor to assume the role, largely matched this text from the series bible, apart from a couple of formatting tweaks. [2] However, the series bible went further, elaborating, "As a young man, he spent time deep sea diving in the Florida Keys, working on an ocean reclamation project. Bold and fearless, this thrill-seeker didn't stop there. His skills at working in a hostile environment, with no gravity, dependant on artificial life-support, would eventually lead to a career in Orbital Engineering, building starships at Utopia Planetia, where he earned a reputation as a trouble-shooter who would take on challenges that most engineers think impossible [....] Spike is a part of our 'troika' [along with Archer and T'Pol]."

Since there was a character on Buffy the Vampire Slayer with the name "Spike", this ENT character's nickname was altered before series pilot "Broken Bow" first aired. The change of nickname was just before "the very end" (in Brannon Braga's words) of the development process. ("Broken Bow" audio commentary, ENT Season 1 DVD/Blu-ray) The nickname was changed to "Charlie", and the alteration was listed as one of six revisions of character names in a one-page "script note" at the start of the final draft teleplay of "Broken Bow" (the page was dated 1 May2001).

In the revised final draft script of "Broken Bow" (dated 11 May 2001), the notion of this character's name being the third consecutive iteration of "Charles Tucker" was not yet established (he was still referred to as having the nickname "Charlie"). When introduced in the same teleplay, he was characterized as being in his "early 30's." The script went on to comment, "[He] is a Southerner who enjoys using his offbeat, often sarcastic sense of humor to disarm people [....] He likes to get a rise out of people." [3] Only later was the character given the full name "Charles Tucker III" and the nickname "Trip".

The role of Tucker ultimately came down to Trinneer and another actor, Eric Close. Close was the studio's preferred choice, due to his work on the short-lived CBS series Now and Again, but Braga preferred Trinneer, who ultimately won the role. (To Boldly Go: Launching Enterprise)

The way Tucker was depicted was obviously influenced by the casting of Connor Trinneer. Regarding how the actor made an impact on the character, Brannon Braga explained, shortly after ENT Season 1 began, "Connor Trinneer is so [...] much funnier than we thought he would be. And he's funnier not when he's making a wisecrack, but when he's put in uncomfortable situations, which we didn't know until he got the role." (Star Trek: The Magazine Volume 2, Issue 9, p. 22)

Charles Tucker III was an early favorite ENT main character of the writing staff. Shortly following the start of the first season, Brannon Braga commented, "I think now we're finding, at least early on, that Trip is really a character that's popping out and with whom we're really having a lot of fun." (Broken Bow, paperback ed., p. 253)

In fact, Brannon Braga continued to approve of how Tucker further developed. Following ENT Season 2, Braga stated, "It's fun to put Trip into awkward situations. You can't go wrong with him because Connor Trinneer's such a talented actor." (Star Trek: Communicator issue 145, p. 26) Concerning how the character is portrayed in ENT Season 3, Braga pointed out, "Trip embodies the idea of people who lost people back on Earth; he's a microcosm of that." (Star Trek: Communicator issue 151, p. 33)

In addition to upgrading Tucker's status from dead to alive, the novels also expand upon the engineer's background. In The Good That Men Do, Tucker's family life is revealed, with scenes involving his parents Charles "Charlie" and Elaine "Gracie" Tucker. The book also mentions Tucker's brother Albert and Albert's husband, as well as provides him with a middle name: Anthony. The novel Last Full Measure depicts an aged Tucker, mentoring a young Larry Marvick, designer of the USS Enterprise (NCC-1701), and, in the final chapter, making his first visit to the Starfleet War Memorial at the same time as 9-year-old Sam and 5-year-old Jimmy Kirk.

Although two episodes (ENT: "Strange New World", "Fusion") state that Trip grew up in Panama City, Florida, the beginning of "The Expanse" clearly shows the Xindi weapon starting its path of destruction in central Florida, around the region of Orlando, and heading south from there, while Panama City is in the Florida Panhandle, approximately 350 miles to the north and west of Orlando. While his sister may have lived in that area as an adult, it would have been impossible for Trip to reminisce about their childhood there while standing at the edge of the destruction, pointing out where the old movie theater had been...not if he had grown up in Panama City.
